Dipolar optimal control of entangled current states
Héctor Briongos-Merino, Felipe Isaule, Bruno Juliá-DÃaz +1
Quantum state control is a fundamental tool for quantum technologies. In this work, we propose and analyze the use of quantum optimal control to exploit the dipolar interaction of…
Bose-Einstein condensation in exotic lattice geometries
Kamil Dutkiewicz, Marcin PÅodzieÅ, Abel Rojo-Francà s +3
Modern quantum engineering techniques allow for synthesizing quantum systems in exotic lattice geometries, from self-similar fractal networks to negatively curved hyperbolic graphs…
Counterflow of lattice polarons in harmonically confined optical lattices
Felipe Isaule, Abel Rojo-Francà s, Luis Morales-Molina +1
We study a mobile impurity in a one-dimensional harmonically confined optical lattice interacting repulsively with a bosonic bath. The behavior of the impurity across baths with su…
Probing dielectric breakdown in Mott insulators through current oscillations
Joan Triadú-GalÃ, Artur Garcia-Saez, Bruno Juliá-DÃaz +1
We investigate the dielectric breakdown of mesoscopic Mott insulators, a phenomenon where a strong electric field destabilizes the insulating state, resulting in a transition to a…
Fermionizing the ideal Bose gas via topological pumping
Maciej Marciniak, Grigori E. Astrakharchik, Krzysztof PawÅowski +1
We investigate the coherence and correlations of many-body states appearing in topological pumping in a one-dimensional Bose gas. By analyzing the system at zero and infinite inter…
Dipolar magnetostirring protocol for three-well atomtronic circuits
Héctor Briongos-Merino, Felipe Isaule, Montserrat Guilleumas +1
We propose a magnetostirring protocol to create persistent currents on an annular system. Under this protocol, polar bosons confined in a three-well ring circuit reach a state with…
